STARTING/CHARGING SYSTEMS
2) Disconnect the connector from terminal M, and
then connect the positive terminal of battery and
terminal M using a lead wire and ground terminal to
starter body.

7. PINION GAP
1) Measure pinion gap while the pinion is pulled out
as shown in the figure.
Pinion gap:
0.5 — 2.0 mm (0.020 — 0.079 in)
(A) Pinion
(B) Gap
(C) Stopper
If the motor is running with the pinion forced end-
wise on shaft, disconnect the connector from termi-
nal M of switch assembly, and then connect
terminal M to ground terminal (−) of battery with a
lead wire. Next, gently push the pinion back with
your fingertips, and then measure the pinion gap.
2) If the pinion gap is outside specified range, re-
move or add number of adjustment washers used
on the mounting surface of switch assembly until
correct pinion gap is obtained.
8. PERFORMANCE TEST
The starter should be submitted to performance
tests whenever it has been overhauled, to assure
its satisfactory performance when installed on the
engine.

STARTER
Three performance tests, no-load test, load test,
and lock test, are presented here; however, if the
load test and lock test cannot be performed, carry
out at least the no-load test.
For these performance tests, use the circuit shown
in figure.
(A) Variable resistance
(B) Magnetic switch
(C) Starter body
1) No-load test
With switch on, adjust the variable resistance to ob-
tain 11 V, take the ammeter reading and measure
the starter speed. Compare these values with the
specifications.
No-load test (Standard):
Voltage / Current
11 V / 90 A max.
Rotating speed
AT: 2,400 rpm or more
MT: 2,800 rpm or more
2) Load test
Apply the specified braking torque to starter. The
condition is satisfactory if the current draw and
starter speed are within specifications.
Load test (Standard):
Voltage / Load
AT: 7.7 V / 16.0 N·m (1.63 kgf-m, 11.8 ft-lb)
MT: 7.5 V / 8.6 N·m (0.88 kgf-m, 6.4 ft-lb)
Current / Speed
AT: 400 A / 740 rpm or more
MT: 300 A / 920 rpm or more
